A temperature compensation circuit according to an embodiment includes a bias circuit configured to output a bias current, the bias current having a current value increasing in proportion to absolute temperature, in a low temperature region in which a temperature is lower than a predetermined temperature, and having another current value increasing at a faster rate than the current value increasing in proportion to absolute temperature, in a high temperature region in which the temperature is equal to or greater than the predetermined temperature, and a transistor having a collector connected to a power supply terminal, an emitter which is grounded, and a base supplied with the bias current.
